# DARPA Is Considering a Nuclear Rocket for Moon Missions

## Nuclear Thermal Propulsion

The Defense Advanced Research Projects Agency (DARPA) just handed out a $14 million dollar contract to develop and test a nuclear thermal space propulsion system (NTP), [*Space.com* reports](<https://www.space.com/darpa-nuclear-thermal-rocket-for-moon-contract>).

The concept is simple: an on-board reactor generates heat, which is then pushed through a nozzle to produce thrust.

The contract, to a company called Gryphon Technologies, is meant to support DARPA's Demonstration Rocket for Agile Cislunar Operations (DRACO) program — essentially a project investigating whether the extreme temperatures produced by nuclear reactions can be used as a propulsion system.

## Covering the Distance

"A successfully demonstrated NTP system will provide a leap-ahead in space propulsion capability, allowing agile and rapid transit over vast distances as compared to present propulsion approaches," Gryphon chief engineer Tabitha Dodsonsaid in [a statement](<https://www.prnewswire.com/news-releases/gryphon-technologies-wins-14m-darpa-task-order-to-support-demonstration-and-development-of-the-high-assay-low-enriched-uranium-nuclear-thermal-propulsion-system-301140093.html>).

[According to DARPA](<https://www.darpa.mil/program/demonstration-rocket-for-agile-cislunar-operations>), an NTP system offers both 10,000 times the thrust-to-weight ratio compared to electric propulsion and two to five times the efficiency of chemical propulsion.

The agency is hoping nuclear thermal propulsion will allow the US to keep up with "maintaining space domain awareness in cislunar space."

## Game Changer

NASA is eyeing a similar system for propelling its own spacecraft. Last year, NASA administrator Jim Bridenstine called NTP a [potential "game changer"](<https://futurism.com/the-byte/nasa-nuclear-propulsion-game-changer>) for the agency, with the potential to revolutionize space travel and enable trips to and the eventual settlement on Mars.

Such a propulsion system could even allow for the generation of artificial gravity during such long trips through outer space, according to [NASA research dating back to 2014](<https://ntrs.nasa.gov/citations/20140017461>), to address the health concerns surrounding long-term exposure to zero gravity.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
